To all whom it may comm.- 1 Be it-known that I, BURNHAMC. STICK- *NIQY, a citizen of the United States, residing 4 in. Elizabeth, in the county of Union and 4 a specification.

State of New Jersey, have invented certain new and .useful Improvements in Type-' WV -iting Machines,- of which the following is My invention relates to chines and is particularly related to v mechanism by which the feed or pressure rolls, which usually bear against the platen in such machines, may be movedto and from said platen. I

My invention is herein disclosed as applied to an Underwood typewriting machine in'whichthe platen is'journaled' in a traveh ing carriage; and the types strike against the front of said platen while the feed or pressure rolls lie beneath said platen, so that a work-sheet may he passed around "said platen from the back and fed .up in front past theprintin point by saidrolls. Said rolls comprise ront and rear rolls, which maybe held against said platen by any usual or, suitable springs. These springs normally holdtherolls against'the platen, andsaid rolls may be moved from the platen or castoff; by meansoffa handle or fingerpiece which operates a rock shaft eXtending,be-

neath theplaten adjacent to the rolls; Said rock shaft is journaled on the rock arms on which one set of said'rolls. are carried and when. said shaft is turned by said handle, tappets or cams fast on said shaft may en- -gage rock arms carrying the other rolls, and
